That massive Gerber multi-tool on your belt probably comes in really handy during emergencies, but not on a catwalk. If you want to be prepared for whatever life throws out you and look fashionable, you'll want to consider Wenger's HypeX line.

Consisting of six stripped down lightweight tools that can be worn as pendants hanging from an included silicone necklace, the HypeX pieces include implements for starting fires, sharpening blades, tightening screws, stripping wires, and of course opening bottles and corks. They'll be available starting in June for around $60 to $100, with more sports-oriented models coming later in the year. [Wenger via Gizmag]
